ART OF DECORATING STONEWARE.

SPECIFICATION forming part of Letters PatentNo. 539,187, dated May 14, 1895.

1 Application filed September 14 1894- To all whom it may concern:

Be it known-that I, AROHIBALD W. PA ULL, of Wheeling, in the county of Ohio and State of West Virginia, have invented a new and useful Improvement in the Art of Decorating, of which the following is a full, clear, and exact description.

The object of my invention is to provide a method for the decorating of stoneware or other ware which cannot be immersed in a liquid in the removalof the paper carrying the pattern.

The transfer of patterns to certain wares has hitherto been impracticable, as a liquid must be applied to remove the pattern-bearing paper, and this liquid entered at the stilt marks and other points and ruined the article. My invention overcomes this difficulty and is an improvement upon the method set forth in my copending application, Serial No. 501,428, filed February 24, 1894.

In practicingmy invention in what I consider its best form, I proceed as follows: Having covered the surface of the paper with a soluble coating, which may be either soluble in water, such as gum arabic, starch or paste, or which may be a substance like pyroxyline varnish, soluble in alcohol and ether or other liquids, I print upon said coating in vitrifiable colors the design or pattern to be trans-.

ferred. I then apply to the surface of the; printed paper a sheet of thin tissue-paper or suitable pliable fabric, preferably paraifined tissue-paper such as that used commonly for wrapping caramels, securing the surfaces together by a coating of material which is liquefiable by heat, such as paraffine, beeswax, or suitable gums, which may be applied either to the pattern or the tissue-paper, but preferably the former; preferably by rubbing a cake of the paraftine, &c., over the surface. Paraffine is very easy to apply and it gives excellent results, so that I deem it preferable to use and intend to claim it specifically, though the broader claims are not limited to its use. As the various substances which can be used successfully as equivalent for paraffine are liquefiable by heat or are of anature which while sufficiently adhesive to hold the pattern temporarily, are less adhesive than the substance by which the pattern is held to the ware. I use these terms in the claim to-de- Serial No. 522,996. (No specimens.)

fine them. The last named coating must not be soluble, at least in the solvent employed for the coating upon which the print is made. Having thus applied the tissue-paper to the pattern, I attack the first coating by its solvent and thus loosen and remove the thick paper, leaving the pattern in colors upon the tissue-paper, or fabric, held thereto by a substance which may be liquefied on the application of heat. This attacking of the first coating is preferably done by immersing the paper in the solvent, first rolling the attached papers into cylindrical form, the patternbearing paper being on the outside of the roll. The pattern is then transferred to the surface to be decorated by coatingflthelatter with an adhesiizematerimsuehlasghlel llllel ll h1E1 iiflliquefylundenheat, or, at least, will not become liquid at the degree of heat necessary to loosen the pattern from the tissue-paper, or fabric. The tissue-paper being then easily fitted to the article, it may be removed in any of the following ways: The article may be subjected to a low degree of heat which liquefies the paraffine or other substance between'the pattern and the paper, leaving the pattern adhering to the film of gelatine on the ware; or the outside of the paper may be rubbed with turpentine, and this, looseuim the paraffine, permits the paper to be drawn 0E; or by allowing the paper to remain on the ware for a sufficiently long time to permit the gelatine to become hard, say for two days or more, the paper may be lifted ed, for the parafline remains soft and has less adhesiveness than the hardened glue. The pattern having been transferred to the ware by any of these modes, the ware is then fired in the usual Way to vitrify the colors and to fix the pattern.

Instead of removing the paper as above stated, I may leave it upon the ware, and

when the latter is put into the decorating kiln the melting of the paraffine willfree the paper,'permitting it to drop off, or to be destroyed by the fire.

The advantages of my invention result from the fact that it may be employed with porous wares which cannot be immersed in a liquid,

giving a simple and effective method for decorating the same.

I claim- 1. The methodof decorating, which consists in printing the pattern uponabody having a E soluble coating, applying it to a second 'pli-i able material by means of a coating of a substance liquefiable by heat, dissolving oi the first named body, applying the pliable material to the ware, and removing the pliable material; substantially as described.

2. The method of decorating, which consists in printing the pattern upon a body ghatvinga soluble coating, applying it to a second pli-' able material by a coating of a substance liqu'efiable by heat, dissolving off the first named a body, applying the pliable material to the ware, and heating the'wareto rem-ovethepl-iable material; substantially as described.

3. The inethodof decoratingmhich consists in printing the pattern upon-a bodyhaviing a j soluble coating, applying it to a second ipliable material by sacoatiing of a substance ltiqi uefiable by heat, tdissol viisng ofi thefirst inamed body, applying the pliable material :to Ware provided with a coating which does not liq-, uefy *by the ihea-tapplied for nemovi'ng tl-ie pliable material, and then heating :the article; substantially :as described.

4. The method of decorating consisting in producing the pattern upon asurfiace, :apply- ,1

in ga second surface to the pattern by means of a substance Fliquefiable by heat, removing the first surface and then applying the pattern to the article and removing the second surface; substantially as described.

5. Themethod of decorating, which consists in printing the patternupona soluble coating mounted on a surface, transferring it to a sec end surface by means of parafiine, and then applying the pattern to the article and removing the surface; substantially as described.

6. Themethod of decorating, which consists A in printing the pattern upon abody havinga soluble coating,transferring it to a second surface by means of an adhesive substance,

applying the sun-face :to the article by an adhesive material of greater itenacit'y than the adhesive substance first 11a1ned,and then removingzsaid surface and leaving thepat-tenn iupon the article; substantially as described.

In testimony whereof it have liereun to set my hand.
